- IMPROVEMENT 1N SAWING-MACHINESQ The Schedule referred to in these Letters Patent and making part of the same.

To all whomtt may concern Be it known that I, GEORGE H. -EDDnEMAAQ of Atlanta, in the county of Fulton, and in the State of Georgia, hare invented certain new and useful Improvements in Combined Circular and Jig-Saw and Lathe; and do hereby declare that the following is a full, clear,

and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the construetion of a machine, which a carpenter', engaged in putting upa house, or doing any other carpenter-Work, can carry with him to the place where such work is being done; also, for the use of cabinet-makers, where alathc;

Figure 2, aside view of the, jig-saw; and

Figure 3 is a side View of the machine, showing bot circular and jig-saw.

A represents a frame, ofl suitable size and material, near the centre of which are two upright standards, B B, strengthened by braces C O, as shown in iig. 3.

On top of the standards B B, a shaft, D is placed, having its bearings in journal-boxes placed thereon, and one end provided with a pulley, E.

On the shaft D is a cani-wheel, F, around which a sectional ring, G, 'is placed; and to the lowerside of this ring a rod, H, is firmly secured.

At the lower' end of the rod H the jig-saw I is pivoted, whichsaw is secured, as usual, in a frame, said frame moving in a groove on a cross-bar in the frame A.

From the pulley E a band, LI, connects with a pulley, K, on a short shaft, L, which has its bearings in a journal-box on the si'de of the frame A, and in the upper end of abent bar, M, which latter is secured to said frame.

In the inner end of the short shaft L isa head, N, in which is secured the shaft on the circular saw O, by means of a set-screw, a', said shaft resting in a journal box on the other side of the frame A.

A table, P, provided with slots, for the two saws to work in, is placed on top of the' frame A.

By removing this table, and the set-screw a inthe head, N, the machine is easily changed' to a lathe. In that case, Ifinsert in the head, N,4 an ordinary lathecentre, placing the back centre, R, at a suitable distance from the former, on the shears, underneath the saw-mandrel, and the tool-rest S on theshears, in the usual manner.

From the pulley K, on the shaft L, a band, T, leads around the driving-wheel U, which is sc cired tothe end of a shaft, V, in the rear part of the frame A.

The machine can be used in a shop where there is steam or water-power, by applying a belt frointhe lineshaftiug in the shop to a pulley to belattached to a balance-wheel, which will be placed on the end; of the j shaft V, which now has the driving-wheel U.

` W'here there is no power, it can be worked by the treadle W, as shown in the drawing-sor by hand, by a handle inserted in the driving-wheel U, -after removing the treadle-attachment.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

'lhe frame A, constructed as herein described,and provided with the eccentric-pulley and shaft D, the short shaft L, one end of which is suitably centred, and the other end provided with a clutch, and the driving-shaft V, whereby I am enabled to form a machine combining in one aY circular saw, a jig-saw, and a lathe, as herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 25th day of July, 1868.

G. H. EDDLEMAN.'
